Shadi,
I've never seen it take 1/2 an hour to synchronize. Usually 5
minutes at the most. What is the stratum of the time server you're using?
I think the lower the stratum, the faster your router will synchronize to
it, because it 'trusts' it more. I don't have the RFC in front of me, but I
think that's how it works.

After NTP has been running, it will store that router's "fudge factor"
as "ntp clock-period" in the configuration which will tend to make
resynchronization faster. Don't remove or edit this line in your
configuration, it's created by the router automagically based on the
specific clock drift of that machine.

Not without buying a more sophisticated router. Most of the lower-cost
and smaller-scale routers don't have an onboard battery-backed clock,
and thus will lose their time setting on a reboot or power-down.
I think you're looking at 3600 series and above for battery-backed clocks.
